Approximate quasi-isodynamicity at a finite aspect ratio in a stellarator vacuum magnetic field

A stellarator vacuum field is found in which, at a finite aspect ratio (A ≈ 40), the contours of the second adiabatic invariant of nearly all particles reflected inside that surface are poloidally closed.
